What is the significance of setting the second parameter to true in json_decode() when decoding a JSON file in PHP?

Setting the second parameter to true in json_decode() when decoding a JSON file in PHP will return the data as an associative array instead of an object. This can make it easier to access and manipulate the data within the JSON file. 

// Read the JSON file
$jsonData = file_get_contents('data.json');

// Decode the JSON data into an associative array
$decodedData = json_decode($jsonData, true);

// Access and manipulate the data as needed
foreach($decodedData as $key => $value) {
    echo $key . ': ' . $value . '<br>';
}
